Re: On -going Drainage Concerns
Dear Mr. & Mrs. Kilgore,
The following is a summary from my site visit earlier today to your property located at
1409 Kings Wood Rd. to view the on -going drainage issues you continue to deal with. I
first visited your property in June of 2021 at your request to view a number of drainage
issues you were experiencing due to the topography of your and your neighbor's lots as
well as some improvements your neighbor had made to their property at 1413 Kings
Wood Rd.
The primary area of concern lies along the southerly, side property line. The neighboring
home sits slightly higher than your home and the natural grade in the area slopes from
south to north, towards your property and then toward the rear of the property. Your
neighbor has installed drain tile from their downspouts in both the northwest and northeast
corners of their home and daylighted them near the side lot line. By doing this they are
discharging a significant amount of extra runoff from their roof toward your property.
The best way to remedy this situation would be for your neighbor to run their drain tile to
their rear yard and discharge it in the direction of their back lot line rather than the side
lot line where it is currently being discharged. This would require the addition of a minimal
amount of drain tile along with changing the alignment of the existing tile but would
substantially reduce the amount of runoff flowing through your property.
If your neighbor is not receptive to the solution proposed above, then I would suggest
modifying your landscaping to better "armor' your property and manage the runoff as it
flows through your property. Along the side of your home you have wood chip mulch, I
would replace the mulch beginning at the point where it meets the grass and extending
in approximately two feet toward your home and running all the way from the front of the
house to the back. In this area I would place larger river rock or fieldstone. The minimum

size of stone should be approximately six inches. In this same area randomly place some
larger boulders (12"-18" dia.+/-) and let them stick out a few inches past the normal border
in order to deflect the water away from your house and also to dissipate some of the
energy. I would place the rock in such a manner that the portion closest to the house is
higher than the portion at the grass line; basically, creating a slope towards the grass. I
would extend this landscape feature at least 3® of the way or farther along your retaining
wall to ensure the runoff makes it past your retaining wall and can safely flow through
your back yard.
Another option would be to construct a berm along your side property line to block the
flow from reaching your landscaping, retaining wall or your home. This would need to be
offset at least a few feet from the property line and could be either vegetated or
landscaped with bushes, rock, etc. Given the topography and water volumes in the area,
I would make the berm at least 18"-24" at the high point. Again, I would start this near
the front of your home and extend it to the back, again, going at least 3/ of the way along
your retaining wall. I understand some of these options may not be too visually appealing
but if done right, I think they could be constructed in such a way that they would fit in with
the surrounding landscape.
I hope this information is helpful. If you or your neighbor have any questions or would
like to discuss things further, please feel free to contact me at 651-675-5641 or
